In mathematics, a Unified Theory of Graph (UTG) is a type of graph theory that allows all that is thought of as fundamental entities and primary properties of graph to be written in terms of nodes and edges both in the physical and digital world.

The postulation of the UTG has led to structure Spacegraph Protocol (SGP) and the construct of Graph Virtual Machine -- a State Virtual Machine (SVM) or Graph Virtual Machine (GVM) that powers SGP and its deployment to all Dapps in Blockchain 3.0
